It's easy to put together. I did it all by myself but I was out of breath and tired so I didn't use it till the next day. It holds up to 330 lb which I am bigger but I get the juice on there I get about 2 minutes on there. It's like a seesaw if you know what that is. It functions good if you got bad knees don't get on there cuz you going to be working out your knee is it comfortable to sit for me yes. The quality is good and it's you can fold it up as well it's easy to move up and down if you can pull up your weight.
